Understanding Public EV Charging Models: How Do You Pay?

As electric vehicles (EVs) become more common, so do public charging stations. But with a variety of payment models and access methods, understanding how to pay for charging can feel overwhelming. In this guide, we’ll break down the different models of public EV charging, from pay-as-you-go to membership-based networks, so you can charge with confidence.

1. Pay-As-You-Go: Simple and Convenient

Pay-as-you-go is the most straightforward model for using public EV chargers. With this option, you simply pay for the electricity you use at the charging station, much like filling up a gas tank. This model offers flexibility, allowing you to charge your EV without any long-term commitment or membership.

  • How It Works: When you arrive at a charging station, you either swipe a credit card, use a mobile app, or scan a QR code to start the charging session. You’ll be charged based on the amount of electricity you use, typically calculated in kilowatt-hours (kWh) or by the minute.
  • Cost: Pay-as-you-go rates vary depending on the charging provider and the type of charger (Level 2 vs. DC Fast Charging). Expect to pay anywhere from $0.10 to $0.50 per kWh, with some stations charging by the minute.
  • Best For: Infrequent chargers or travelers who prefer not to commit to a single charging network.

This model is common at many independent charging stations, as well as some locations within larger networks.

2. Membership-Based Networks: Charging with Perks

Membership-based networks offer more than just charging; they provide access to a large network of stations and often include perks like discounted rates, priority access, and real-time availability updates. By signing up for a membership, you gain access to a specific charging provider’s network.

  • How It Works: To use a membership-based network, you need to sign up with the provider (e.g., ChargePoint, EVgo, Electrify America) either through their website or mobile app. Members typically receive a key fob or RFID card that can be used to activate charging stations.
  • Cost: Membership plans vary. Some networks offer a free basic membership, while others require a monthly fee. Members usually benefit from lower per-session costs compared to pay-as-you-go users, and some networks offer flat-rate subscriptions for unlimited charging.
  • Best For: Frequent EV drivers who want access to a wide range of charging stations with potential cost savings.

For example, EVgo offers a subscription plan that lowers per-minute charging rates, while ChargePoint allows users to find and access stations using their app or RFID card.

3. Free Public Charging: A Welcome Bonus

Yes, free public charging stations do exist! These are often provided by businesses or municipalities as a way to attract EV drivers and promote sustainability. Free chargers can be found at retail locations, restaurants, hotels, and some public parking facilities.

  • How It Works: Simply plug in and start charging—there’s no cost to you. Some free stations may require you to check in with a front desk or use an app to activate the charger, but many allow you to charge with no additional steps.
  • Cost: Free!
  • Best For: Anyone who loves a good deal or wants to take advantage of complimentary charging while shopping, dining, or staying at a hotel.

Keep in mind that free chargers may have longer wait times, especially in busy areas, and are often slower Level 2 chargers.

4. Subscription-Based Charging: Unlimited Access

Some charging networks offer subscription-based charging models, allowing users to pay a flat monthly or annual fee for unlimited access to charging stations. This model can be highly cost-effective for drivers who regularly use public chargers.

  • How It Works: You pay a recurring fee for unlimited charging at participating stations. This model is particularly common in workplace or apartment complex charging setups, where the cost is built into a larger service package.
  • Cost: Subscription fees range from $20 to $50 per month, depending on the network and level of access. Some plans offer unlimited Level 2 charging, while others may include access to DC Fast Chargers at a reduced cost.
  • Best For: EV drivers who regularly rely on public chargers for their daily commute or travel needs.

Electrify America, for example, offers a Pass+ subscription that provides discounted rates on fast charging sessions, while some workplace charging programs offer flat-rate plans to employees.

5. Charging-as-a-Service (CaaS): Workplace and Residential Solutions

Charging-as-a-Service (CaaS) is a model typically used by workplaces, apartment complexes, and commercial properties. With CaaS, a company or property owner contracts with a charging provider to install and manage charging stations on their premises, offering them to employees, tenants, or the public.

  • How It Works: Users typically access the chargers via a mobile app or RFID card, and the cost is either paid directly by the user or subsidized by the company or property owner.
  • Cost: Pricing varies widely based on the contract between the charging provider and the property owner. Some offer free charging to employees or tenants as a perk, while others charge a usage fee.
  • Best For: Employees, residents, or customers at locations that offer on-site charging.

This model is popular with companies looking to support green initiatives and with property developers seeking to attract environmentally-conscious tenants.

6. Roaming Networks: Cross-Network Access

As more charging networks pop up, some providers are partnering to offer cross-network access, also known as roaming. This allows EV drivers to use stations across different networks without needing separate memberships for each one.

  • How It Works: With a roaming agreement in place, your membership with one charging network allows you to use stations from other networks. You pay through your primary account, even if the charger belongs to a different provider.
  • Cost: Roaming fees may apply, but they are usually minimal. In some cases, you’ll pay the same rate you would on your home network, while in others, you may be charged a small premium.
  • Best For: EV drivers who want flexibility and access to a broader range of charging stations without needing multiple accounts.

An example of this is the partnership between ChargePoint and EVgo, which allows members of either network to use both sets of chargers with a single account.

Choosing the Right Charging Model for You

With so many public EV charging models available, the right one for you will depend on your driving habits and charging needs. If you’re a frequent traveler, a membership or subscription plan with a major network might offer the best value. For casual drivers, pay-as-you-go or free public chargers could be more convenient.

As EV infrastructure continues to expand, more options are becoming available to meet the needs of all types of drivers. Knowing how each model works will help you make informed decisions and keep your EV powered up wherever the road takes you.
